概要

What is ArcGIS MCP Bridge?

A secure, local-first, asynchronous MCP server exposing ArcGIS Pro’s ArcPy engine to Claude Desktop and other MCP hosts over stdio JSON-RPC. It provides 100 declarative geoprocessing tools across 10 verticals with a two-process isolation architecture that keeps the MCP protocol layer separate from the licensed ArcPy runtime.

How to use ArcGIS MCP Bridge?

Install the package via pip install arcgis-mcp-bridge or uv pip install arcgis-mcp-bridge. Set the required ARCPY_PYTHON_PATH environment variable to the licensed worker interpreter, optionally configure ARCGIS_MCP_ALLOWED_ROOTS and other settings, then add the server to your Claude Desktop configuration with the command arcgis-mcp-server. After restart, call health_check first to verify the full pipeline.

Key features of ArcGIS MCP Bridge

  • 100 declarative geoprocessing tools across 10 verticals
  • Two-process architecture isolating arcpy from the MCP server
  • PathGuard sandbox enforcing read/write boundaries on filesystem access
  • Destructive mutation safety floor requiring explicit confirm tokens
  • Sketch-to-GIS pipeline for hand-drawn polygon digitization
  • 81 unit tests with mocked arcpy for CI verification

Use cases of ArcGIS MCP Bridge

  • Buffer parcels, dissolve layers, or run kernel density from natural language prompts
  • List, describe, and manage feature classes in enterprise or file geodatabases
  • Calculate slope, aspect, and hillshade from DEM rasters
  • Find nearest facilities or compute OD cost matrices using network analysis
  • Convert hand-drawn sketch to a GIS feature class via the vision analytics pipeline
